Problems solved by technology

The coal charging sealing mud of the existing 7.63m coke oven is set on the sixth floor of the coke oven coal tower (elevation 26m). After the coal is loaded, it enters the furnace area. Due to the small amount of mud reserves on the coal loading car, the frequent use of materials is complicated, and because the mud is not stirred when it is on the coal loading car, it is easy to settle and solidify, and the pipeline is blocked, which makes the coal charging hole Insufficient sealing, smoke and environmental impact

Embodiment 1

[0031] This embodiment is realized on the device embodiment.

[0032] The embodiment of this coke oven coal charging hole sealing method can be found in figure 1 , which includes the following sequential steps:

[0033] 1. Open the agitator 3 installed in the mud tank 2 to make the mud stir evenly; the ratio of ash and water in the present embodiment is 1:7;

[0034] 2. The opening and closing device 18 of the first coal charging hole cover sends the first coal charging hole cover 19 into the coal charging hole, and closes the coal charging hole;

[0035] 3 Open the mud tank solenoid valve 4 and the first slurry inlet solenoid valve 15, close the second slurry inlet solenoid valve 8, the mud flows from the first mud pipe hose 16 to the opening and closing device 18 of the first coal charging hole cover by its own weight, and injects To the sealing groove between the first coal charging hole cover 19 and the seat;

[0036] 4 After 16 seconds, close the mud tank solenoid valv...

Embodiment 2

[0041] This embodiment is realized on the device embodiment.

[0042] The embodiment of this coke oven coal charging hole sealing method can be found in figure 1 , which includes the following sequential steps:

[0043] 1. Open the agitator 3 installed in the mud tank 2 to make the mud stir evenly; the ratio of ash and water in the present embodiment is 1:7;

[0044]When the sealing operation of the second coal hole cover 12 and the first coal hole cover 19 is carried out continuously, the present embodiment is directly carried out by the following step 2, and the step 1 of the present embodiment is not needed.

Abstract

The invention relates to a coke oven coaling hole sealing device and a sealing method of the coaling hole. The device comprises two coal car hoppers, a mud tank, a mud hard pipe and two mud flexible pipes. A tilt angle of each mud flexible pipe is not less that 60 degrees in a horizontal direction, a compressed air control solenoid valve is installed on the mud hard pipe, and the other end of the compressed air control solenoid valve is connected with a compressed air pipe. The sealing method of the coaling hole comprises a step of opening a stirrer installed inside the mud tank; a step of sending a coal-charging hole cover to the coal-charging hole through one of an off-and-on device of the coal-charging hole cover and opening the coal-charging hole; a step of opening the solenoid valve of the mud tank and a mud-entering solenoid valve, closing another mud-entering valve and injecting the mud into sealing grooves of the coal-charging hole cover and a coal-charging base; a step of closing the solenoid valve of the mud tank, opening a control solenoid valve used for compressing air and emptying the mud soft pipe; a step of packing up the sealing device of the off-and-on device of the coal hole cover. The sealing device and the sealing method enable sealing mud of the sealing grooves of coal-charging hole cover and the coal-charging base to be uniform.

Description

[0001] technical field [0002] The invention relates to a sealing device and a sealing method for a coal charging hole of a coke oven, in particular to a sealing device and a sealing method for the gap between a coal charging car hole cover and a seat of a 7.63m coke oven. Background technique [0003] The coking process is a process in which coal is dry-distilled under the action of high temperature in an air-isolated space to produce raw gas, coke and heat energy. When the coal is loaded into the carbonization chamber, the gap between the coal charging hole cover and the seat must be sealed, so that the carbonization chamber becomes a closed space isolated from the outside air, preventing air from entering the coke oven carbonization chamber through this gap to burn the coal; The raw gas produced during the dry distillation process escapes to the atmosphere through this gap, causing environmental pollution. The coal charging sealing mud of the existing 7.63m coke oven is...
